Upload events
The uploader emits three events during each upload. These can be subscribed to for any use case when tracking upload progress is needed.
chunkUpload: Emitted whenever a chunk is uploaded.chunkError: Emitted whenever a chunk upload fails. Due to internal retry logic, these errors can most likely be ignored as long as the upload doesn't error overall.done: Emitted when the upload completes.
uploader.on("chunkUpload", (chunkInfo) => {
console.log(
`Uploaded Chunk number ${chunkInfo.id}, offset of ${chunkInfo.offset}, size ${chunkInfo.size} Bytes, with a total of ${chunkInfo.totalUploaded} bytes uploaded.`,
);
});
uploader.on("chunkError", (e) => {
console.error(`Error uploading chunk number ${e.id} - ${e.res.statusText}`);
});
uploader.on("done", (finishRes) => {
console.log(`Upload completed with ID ${finishRes.id}`);
});
